Abstract (en)
[origin: WO2018007710A1] The invention relates to a method for liquefying natural gas comprising a mixture of hydrocarbons, including mostly methane, the method comprising a first refrigerant cycle semi-open to the natural gas in which the possible liquids from the natural gas which have been condensed are separated from the natural gas input stream, the latter then passing through a main cryogenic heat exchanger (4) in order to contribute by heat exchange to the pre-cooling of a main stream of natural gas (F-P) and to the cooling of an initial stream of refrigerant gas (G-0), a second refrigerant cycle semi-open to the natural gas in order to contribute to the pre-cooling of the natural gas and the refrigerant gas as well as to the liquefaction of the natural gas, and a refrigerant cycle closed to the refrigerant gas in order to provide the sub-cooling of the liquefied natural gas and to provide a cooling power that complements the other two cycles. The invention also relates to a facility for liquefying natural gas for implementing such a method.
Abstract (fr)
L'invention concerne un procédé de liquéfaction d'un gaz naturel comprenant un mélange d'hydrocarbures dont majoritairement du méthane, le procédé comprenant un premier cycle réfrigérant semi-ouvert au gaz naturel dans lequel les éventuels liquides du gaz naturel qui ont été condensés sont séparés du flux d'alimentation de gaz naturel, ce dernier traversant alors un échangeur de chaleur cryogénique principal (4) pour contribuer par échange thermique au pré-refroidissement d'un flux principal de gaz naturel (F-P) et au refroidissement d'un flux initial de gaz réfrigérant (G-0), un second cycle réfrigérant semi-ouvert au gaz naturel pour contribuer au pré-refroidissement du gaz naturel et du gaz réfrigérant ainsi qu'à la liquéfaction du gaz naturel, et un cycle réfrigérant fermé au gaz réfrigérant pour assurer le sous-refroidissement du gaz naturel liquéfié et fournir une puissance de réfrigération complémentaire aux deux autres cycles. L'invention concerne également une installation de liquéfaction de gaz naturel pour la mise en œuvre d'un tel procédé.
